What good does a marigold plant do to repel pests in a garden?
Answers:
Most bugs do not like any form of marigolds, therefore using them as a border around other plants or even just near other plants tends to direct the bugs to a different area, thus protecting the plants. However, even dish soap such as Dawn in a sprayer attached to your hose will make the bugs move to your neighbors yard. In cases of real determined bugs the use of the juice from hot peppers sprayed on the plants certainly changes the bugs mind.

you plant them near vegetable plants. it keeps the bugs off of the vegetables. it prevents having to use pesticides. some vegs. have lots of bug pests that reduce yields and quality.
Mosquitos don't like them!
the strong fragrance of the flower helps... along with chemicals the roots secrete and plants around them absorb... its almost like a systemic deterrent... if you plant them with tomatoes they ward off whiteflies
if you pick one and break open a flower,youll see that they smell bad like a skunk,therefore animals and insects dont like them,they are beautiful flowers,but they stink.and they do a good job at repeling animals and insects!
Nothing. It is a bit of folk lore that gets bandied about. The one study I read had broccoli doing far worse in terms of crop yield without the companion planting of marigolds.
